Place of the largest explosive detonation in the world

On April 18, 1947 British engineers attempted to destroy the entire island in what became known as the "British Bang" (or "Big Bang"). 4,061 (another source claims 6,800) tons of surplus World War II ammunition were placed in various locations around the island and set off. The island survived, although the extensive fortifications were destroyed. The blast was listed in the Guinness Book of World Records under largest single explosive detonation.
